Odd battery activity after flashing roboto font

heres what happened
i turned my phone on, had 100%.
dled the font of the internet
did a nandroid backup with rom manager and cwk (which usually takes around 7 min)
flashed the font
turned phone on, font is awesome, and i still had 100%. odd isnt it
its been on for 3 hours, with mostly standby usage and is 97% now. this obviously is not normal nor correct.

what i think happened is that the ones digit is now the tens digit for the 10% battery increments. which makes no sense because a font probably would not mess with the battery increments.
